ER410NiMo ndi waya wolimba wachitsulo chosapanga dzimbiri wa martensitic wokhala ndi mankhwala okhala ndi 11.0 – 12.5% ​​Cr, 4.0 – 5.0% Ni, ndi 0.40 – 0.70% Mo. Ndi yoyenera kuwotcherera ndi mpweya (monga TIG/MIG) m'malo onse. Pakuwotcherera, arc imakhala yokhazikika, ndipo chitsulo chosungidwacho chimakhala ndi kukana kwabwino kwa cavitation, kukana kutayika kwa mchenga,

ndi makhalidwe a makina. Kutentha nthawi zambiri sikofunikira musanawotchele; kutentha pambuyo pa kuwotcherera (PWHT) pa 580 ~ 620℃ kwa maola awiri (kutsatiridwa ndi kuzizira kwa mpweya, AC) kumalimbikitsidwa malinga ndi zofunikira pakugwiritsa ntchito. Chitsulo choyikidwacho chimatha kupangidwa ndipo chimayenera kugwiritsidwa ntchito pazida zopanikizika.

Zopangidwira kuwotcherera zitsulo zopangidwa ndi ASTM CA6NM, chitsulo chosapanga dzimbiri cha 410/410S/405, ndi zitsulo zina zofanana za 13%Cr – 4%Ni. Ntchito zambiri zimaphatikizapo zida zopondereza (zogwirizana ndi miyezo ya zotengera zopondereza), masamba a turbine, ma valve, mapaipi opondereza kwambiri, ndi zida zomangira zomwe zimafuna dzimbiri ndi kukana kuwonongeka.

Zindikirani

1. Onetsetsani kuti pamwamba pa waya pali poyera komanso palibe mafuta, dzimbiri, kapena chinyezi musanagwiritse ntchito kuti mupewe kusokoneza ubwino wa kuwotcherera.

2. Sungani mpweya woyera komanso kuthamanga koyenera kuti mupewe kusweka kwa mpweya ndi kusweka komwe kumabwera chifukwa cha haidrojeni.
